Martin Storsjö e23317c9da [libcxx] [test] Adjust separator form in fs.op.absolute for libc++ on windows
This test was previously tweaked in
321f696920 to match the output of
of MS STL (except that the MS STL fails on the testcase with an
empty path).

libc++ doesn't produce paths with all normalized separators (and the
spec doesn't mandate it to either).

Tweak the test reference to match exactly what libc++ produces. If
testing with a non-libc++ library, do a relaxed comparison that allows
the separators to differ.

Martin Storsjö 52c5f5ad5f [libcxx] [test] Fix building create_directory in MSVC configurations
Don't use the mode_t type - the official windows sdk doesn't have that type.
(Mingw headers does have such a typedef though.) The umask function returns
int on windows, in both header variants.

Thus just use auto to deduce the umask return type automatically.

Martin Storsjö 714644a36c [libcxx] [test] Move the is_<platform> functions down to subclasses
If cross testing (and manually specifying a LIBCXX_TARGET_INFO in the
cmake configuration, as the default is to match the build platform),
we want the accessors for querying the target platform, is_windows,
is_darwin, to return the right value depending on which target info
class is used, not based on what platform is running the build and
driving the tests.

When LIBCXX_TARGET_INFO isn't defined, the right target info class
is chosen automatically based on the platform one is running on, so
this shouldn't make any practical difference for such setups.

Martin Storsjö 29012ce986 [libcxx] Map ERROR_BAD_PATHNAME to errc::no_such_file_or_directory on windows
Opening a path like \\server (without a trailing share name and
path) produces this error, while opening e.g. \\server\share
(for a nonexistent server/share) produces ERROR_BAD_NETPATH (which
already is mapped).

This happens in some testcases (in fs.op.proximate); as proximate()
calls weakly_canonical() on the inputs, weakly_canonical() checks
whether the path exists or not. When the error code wasn't recognized
(it mapped to errc::invalid_argument), the stat operation wasn't
conclusive and weakly_canonical() errored out. With the proper error
code mapping, this isn't considered an error, just a nonexistent
path, and weakly_canonical() can proceed.

This roughly matches what MS STL does - it doesn't have
ERROR_BAD_PATHNAME in its error code mapping table, but it
checks for this error code specifically in the return of their
correspondence of the stat function.

Martin Storsjö c793f68d9b [libcxx] Don't use dllimport for a static member in a template
This fixes clang warnings (that are treated as errors when running
the test suite):

libcxx/include/string:4409:59: error: definition of dllimport static field [-Werror,-Wdllimport-static-field-def]
               basic_string<_CharT, _Traits, _Allocator>::npos;

The warning is normally not visible as long as the libc++ headers
are treated as system headers.

The same construct is always an error in MSVC.

(One _LIBCPP_FUNC_VIS was added in
2d8f23f571, which broke DLL builds.
59919c4d6b fixed this by adding another
_LIBCPP_FUNC_VIS on the declaration for consistency, but the underlying
issue remained, that one can't use dllimport here.)

Martin Storsjö 34ee3d91a8 [libcxx] [test] Pass some windows environment variables through to test processes
Normally, the run.py wrapper script runs the child processes in
a clean environment, with only the environment variables available
that are passed via the --env parameter.

However, the COMSPEC and TEMP variables are kind of necessary when
running some tests; COMSPEC is necessary for finding the interpreter
when executing commands via std::system().

Before f1a96de1bc, tests were executed
via an intermediate shell which implicitly readded the COMSPEC variable.

The TEMP variable allows temp files to be placed in a sensible
location; if unset, they're placed in the default temp fallback of
